Griff and Kendo pay tribute to former Knight John Cannon.

Many of you will have heard of the tragic passing of former Knight John Cannon over the weekend following a suspected heart attack.

John, or JC as he was affectionately known to many, joined the Knights from Coventry in 2005 and spent two years with the Club before being forced to retire from the game following a series of concussions.

The Canadian international, who gained 31 caps, was renowned for being a hard-hitting, powerful number twelve and was once described as “the best centre outside the Premiership in England” by Rugby World magazine.

Griff, who was Director of Rugby at Castle Park for much of John’s spell with the Club paid tribute to the well-liked former Knight stating. "I was devastated to learn of John’s passing, he was a larger than life character, truly uncompromising on the field and a much underrated player. It is truly sad news for all those who’ve had the pleasure of coaching and playing alongside him.”

Kenworthy, who lined up alongside John in the Doncaster blue, red and white many times added. “John was a really tough player on the pitch and top bloke off it, he’ll be greatly missed and our thoughts are with his family during this difficult time.”
